摘　　要：根据渐开线斜齿轮传动啮合特点,将其等效为一对反向圆锥滚子接触,基于Archard磨损计算公式建立其在干摩擦状态下的准静态齿面粘着磨损计算模型,对其齿面磨损特性进行数值仿真,并在此基础上进一步分析齿宽、螺旋角、转矩以及载荷循环次数等参数变化对齿面累积磨损深度的影响。结果表明:干摩擦状态下,斜齿轮传动系统中主动轮齿面磨损深度大于从动轮,最大齿面磨损深度出现在主动轮齿根啮合位置;转矩、齿宽与载荷循环次数变化对齿面磨损分布影响较大,螺旋角变化对齿面磨损分布影响较小。According to the meshing characteristics of involute helical gear transmission,it is equivalent to a pair of reverse tapered roller contact.Based on the Archard wear calculation formula,the quasistatic tooth surface adhesion wear calculation model under dry friction state was established,and the tooth surface wear characteristics were numerically simulated.On this basis,the influences of changes of tooth width,helix angle,torque and load cycle times on the cumulative wear depth of tooth surface were analyzed.The results show that under the dry friction condition,the tooth surface wear depth of the driving pinion is greater than that of the driven gear,and the maximum tooth surface wear depth appears at the root of the driving pinion.The changes of torque,tooth width and load cycles have great influence on the tooth wear distribution,while the changes of helix angle have little influence on the tooth wear distribution.
